This section describes the functionality of most of the listed features as they pertain to this
server board. For more detail information, see the Intel
®
Enterprise South Bridge 2 External
Design Specification.
3.3.1 Serial ATA Support
The Intel
®
6321ESB I/O Controller Hub has an integrated Serial ATA (SATA) controller that
supports independent DMA operation on six ports and supports data transfer rates of up to 3.0
Gb/s. The six SATA ports on the server board are numbered SATA-0 through SATA-5. The
SATA ports can be enabled/disabled and/or configured by accessing the BIOS Setup utility
during POST.
The BIOS initializes and supports SATA devices just like PATA devices. It initializes the
embedded IDE controllers in the chipset and any SATA devices that are connected to these
controllers. From a software standpoint, SATA controllers present the same register interface as
the PATA controllers. Hot plugging of SATA drives during the boot process is not supported by
the BIOS and may result in undefined behavior.
3.3.1.1 Intel
®
Embedded Server RAID Technology II Support
The on-board storage capability of this server board includes support for Intel
®
Embedded
Server RAID Technology II, which provides three standard software RAID levels:
Data striping (RAID Level 0)
Data mirroring (RAID Level 1)
Data striping with mirroring (RAID Level 10)
For higher performance, data striping can be used to alleviate disk bottlenecks by taking
advantage of the dual independent DMA engines that each SATA port offers. Data mirroring is
used for data security. Should a disk fail, a mirrored copy of the failed disk is brought on-line.
There is no loss of either PCI resources (request/grant pair) or add-in card slots.
With the addition of an optional Intel
®
RAID Activation Key (Intel Part # AXXRAKSW5), Intel
®
Embedded Server RAID Technology II is also capable of providing fault tolerant data striping
(software RAID Level 5), such that if a SATA hard drive should fail, the lost data can be restored
on a replacement drive from the other drives that make up the RAID 5 pack.
See Figure 2 for the location of the Intel
®
RAID Activation Key connector location.
